1. What is the Width of Dodecagon?

The Width of a Dodecagon is the horizontal distance from the left most edge to the right most edge of the Regular Dodecagon. It is an important geometric measurement used in various mathematical and engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Width = \frac{(2 + \sqrt{3}) \times Diagonal\ Across\ Three\ Sides}{\sqrt{3} + 1} \]

Where:

\( Diagonal\ Across\ Three\ Sides \) — The diagonal measurement across three sides of the dodecagon (in meters)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)

Explanation: This formula establishes a mathematical relationship between the diagonal across three sides and the width of a regular dodecagon, utilizing the properties of square roots and geometric proportions.

3. Importance of Width Calculation

Details: Calculating the width of a dodecagon is crucial in geometric design, architectural planning, and various engineering applications where precise measurements of regular polygons are required.

4. Using the Calculator

Tips: Enter the diagonal across three sides measurement in meters. The value must be positive and valid for accurate calculation.
